Summary0013808: Please add 64-Bit ARM endianness defines to cmake
DescriptionWhen building for 64-Buit ARM (officially known as Aarch64), cmake will fail to build due unknown byte order.

In file included from /data/oe/build/tmp-eglibc/work/aarch64-oe-linux/cmake/2.8.10.1-r0.0/cmake-2.8.10.1/Utilities/KWIML/test/test_ABI_C.c:13:0:
/data/oe/build/tmp-eglibc/work/aarch64-oe-linux/cmake/2.8.10.1-r0.0/cmake-2.8.10.1/Utilities/cmIML/ABI.h:419:3:

error: #error "Byte order of target CPU unknown."

With the attached patch, cmake tests pass on the ARMv8 Foundation model simulator.
Steps To Reproducemkdir oe
cd oe
git clone git://git.linaro.org/openembedded/meta-aarch64.git [^]
# the last commit has already the attached patch, so rewind from head
git checkout 54d06ed77b0cc11ac1e260ee0ab9751f9ed2c4ed
# this will clone and install a lot of stuff - debian/ubuntu expected.
bash meta-aarch64/scripts/init.sh
cd openembedded-core
. oe-init-build-env ../build
bitbake cmake

The bitbake command will take a long while, as it will compile the crosscompiler and all tools first.

This instruction is based upon the following page:

Thanks! Both KWIML and KWSys are shared with other projects so the entry point for changes is not through CMake. I've split your patch into one for each of the two projects. The KWIML one is here:

 http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=34916522 [^]

I'll report back again once the KWSys commit is ready.
